T all whom. it may concern.

Be it known that I, RAYMOND G. BULLOGK, a` citizen of the United States,residing at Baltimore, in the county of Baltimore and State of Maryland,have invented certain new andv useful Improvements in Single- UnitKnockdown Sections, 'of which the following is a specification.

The object of this invention is to provide anew and improved 'form of'one drawer metal filing section.

This and other objects of the invention will be fully illustrated inthedrawings, described in the specification and pointed out inthe claims atthe end thereof.

.ln the drawings, like reference numerals indicate like: parts.

ln the" drawings, reference numeral 1 indicates the case of the unitdrawer section, comprising a base 2, a body structure 3, a to) 4 and adrawer 5. The base 2 is formed of two sheets of metal, the blank for thefront portion being indicated at 6 and the blank for the rear portionbeing indicated -at 7. rlhe blank for the front portion of the base isbent to form the foot 8, the top 9 and the front panel 10. .The blankfor the portion is bent to form the top 11, sides 12 and 13, the feet 14and 15, the back wall 16 with the foot 17. The forward edge of the sideis bent in as shown at 18 and 19 to form ribs which have the appearanceof uprights. The front part of the base is joined to the rear part byinserting it from below so that the top 9 of the forward section engagesunder the top 11 of the rear section and supports it. The top 9 is forthat purpose provided with a fillet so that a portion of the top 9extends under the top 11 and the two parts of the base are spot weldedor otherwise suitably fastened together.

The flanges 18 and 19 serve as guides to hold the front o-f the base inplace.

The body section is made up of four uprights, 2() and 21 at the frontand 22 and 23 at the bac-k. The uprights 20 and 21 are channel shapedwith the channels opening rearwardly and outwardly and the uprights 22and 23 are angle irons with the flanges extending outwardly. y Theuprights 2O and 21 are formed as indicated in Figures 36 and 37 and theuprights 22 and 23 are formed as indicated in Figures 38 and 39. Theuprights 20 and 21 are provided with angles or spacers 24 weldedthereto, (see Figure 13), the flange of the spacer being spaced a smalldistance from the bottom of the channel so as to leave room for theflange 25 on the end when the end is inserted. The uprights 22 and 23are provided with angles spot welded thereto in the same manner and forthe same purpose.

The uprights 2O and 21 are joined together at the top by the top strikeshown in Figures 29-32 and are joined together at the bottom by thebottom strike shown in Figures 33, 34 and 35, the overlapping partsbeing welded together. The bottom strike 40 is bent up from a blank 41shown in Figure 33. This strike at the forward end is provided with thechannel 42 and on each side has an extension bent down to form a flange43 and an extension bent up to form a. flange 44. The uprights areplaced inside of the flanges 44 and are welded to them. The tops of thefront uprights 20 and 21 have extensions 35 and 36 formed thereon andthe bottoms have extensions 34 thereon. rlhe extension 34 forms thefront and the outside of the channel, the inside of the channel beingcut away. The extension 36 is provided with a flange 37 bent inwardly inthe bottom. Pivotally mounted to the Fach of the rear uprights 22areprovided with an extension 38 at the bottom and with an extension 39at the top. The extension y 38 engages inthe channel formed at thebottom of the back as shown in Figures 6 and3 and the flanges 39 engagein front of the flange 59 bent up from the back. at the top. See Fig.9.. The rear uprights are perforated as indicated at `63 vin Fig. 38 toreceive the extensions 62 on the guide plate 6G for the lockingapparatus. f

The uprights and 22 are connected together at the bottom by the guide 26of the roller suspension and the uprights 21 and 23 are connected in thesame manner. In this way, the front and back frames of the case 'arejoined together. Any number of the roller suspension guides may be usedfor this purpose. The uprights are provided with openings 27, 28 and 29,into which project suitable lugs 30, 31 and 32, formed on the guide, theuprights and the guide being locked together by a ke 33.'

It will be underst'oo that while but one big` drawer is shown,.thesection may be pro vided with several smaller drawers instead, each ofwhich drawers will require two guides for its roller suspension so thatthe uprights on each side, fro-nt and back will be held together by twoguides. If but one drawer is used in the section, an idle guide can beused at the top or simply a bar might be used interlocked with theuprights in the same way as are the guides.

At th'ebottom of the back plate is provided the notch 52 and at the topis pro-A vided the notch 53 for locking mechanism. Nested in the opening67B is provided the angle. reinforce or fastener 54 which is welded tothe back. On the base 11 is provided a locking clip or support 55 forthe fastener 54; This clip is perforated as shown in Fig. 10 to receivethe tongue 56 which goes thru the opening therein. The base isperforated to receive the locking clipv as shown at 57 in Fig.' 14. Theparts come. together at the back as shown in sectional elevation in Fig.6. See also Fig. 1() for a front sectional elevation and Fig. 11 for atopy plan view. At the top the back is bent inwardly with a flange 58and upwardly with a flange 59. The guide plate 60 for the lockingapparatus is welded to the flange 58. This plate 60 is angle shaped,being provided with the flange 61 that bears against the back. Theplate` 60 is provided with an extension 62 which passes thru an opening63 in the top of the upright 22 shown at the top of Fig. 38 and thisextension is bent down as `shown in dotted lines in Fig. l9, and in thisway the uprights 22 and 23 are locked to-gether with thev guide .plate60 and the back`51.

` The top of the case is formed from a single piecexof metal bent withflanges on four sides thereof and flanges projecting inwardly from thebottom of the sides forming a channel shaped rim all around.

At the back, the top is provided with the vertical flange 64 on thebottom of which i's provided the inwardly projecting flange 65 on whichis provided the extension 66 which pass thru openings 67, 67, in theflange formed on the top of the back so that by this engagement the topis locked to the? b-ack. At the front the vertical flange 67A isprovided with the inwardly projecting flange 50 on top of which engagesthelockj ing buttons 49 pivotally mounted on the top strike against thefront of which the flange 5() makes a close fit.

. The body makesk engagement with the base at the back by means of thetongues 56 as shown in Figs. 6 and 10 and the body is fastened tothebottom at the front by the engagement of the buttons 69, pivotallymounted on topi of the bottom section as shown in Fig. 7, the forwardends of which buttons pass thru a slotted clip 70, shown in Figs. 23-26,inclusive, and engage with the lower flange of the bottom strike 40 asshown in Fig. 7.

The ends 71, 71, are formed from the blank 72 shown in Fig. 43, the endas formed being shown in Figs. 44, 45 and 46. These ends are inserted inthe channels that are formed Vat the front of the oase on the uprights2O and 21 and at the backof the case in the channels formed between theuprights 22 and 23 and the flanges ,on the sides of the back plate` 51.vThe end `is moved edgewise to position by being inserted either from thetop or the bottom, and if inserted from the top, the cover is put in.place thereafter. i

The front frame is reinforced in corners by reinforcements 73 at top and74 at bottom, shown in Figs. 7, 8, ll, 13, v51, 52, 53 and 54. l v

It will be understood that'this unit is made knock-down so that a numberof bases' can be shipped separately in one package, a number of tops inanother package, the top and bottom strikes in another package, the backand parts attached thereto in another package, the front uprights inanother package, thecconnections between the front uprights and backs inanother package, and other details will be Iinade up into otherpackages. `It will be understood that the les case can be assembled atthe factory and shipped complete but-a large number of cases assembledand shipped complete will take up much inore space and cost more than ifthe cases are knocked down and the parts are shipped separately, asabove described. vWhen the shipment has reached its destination, thevarious parts can be unboxed and grouped in the warehouse, and kept asopen stock, saving storage room, and the pieces can be assembled andldelivered as fast as the cases are needed.
